Cranial Neuropathies What are cranial neuropathies? Nerves power your entire body, but those nerves can be damaged by injury or an illness such as diabetes. Neuropathy is a disorder that causes nerve damage and affects your ability to feel and move. Exactly how your body and your movement are affected depends on where in the body the damaged nerves are located. When nerves in the brain or brainstem are affected, it is called cranial neuropathy. The cranial nerves are those that arise directly from your ...

There was no ataxia, areflexia, limb weakness or sensory involvement. Serum anti-GQ1b IgG antibody was present. Treatment with intravenous immunoglobulin started, and the patient responded with a rapid resolution of symptoms. The diagnosis is consistent with polyneuritis cranialis which is considered to be a Guillain-Barre syndrome variant, a forme fruste, but very rare. The diagnosis can be difficult and a thorough investigation is required. Electrophysiological examination, laboratory evaluations, imaging and cerebrospinal fluid examination are often required in the investigations. Cranial neuropathy can be the presentation of many disorders. Determination of anti-ganglioside antibodies as anti-GQ1b is valuable to the diagnosis, and shows the association with the Guillain-Barre syndrome.}, author = {Edvardsson, Bengt and ...
FINAL DIAGNOSIS:. CMV ventriculo-encephalitis, polyradiculitis, and multiple cranial neuritis. DISCUSSION. CMV has been associated with a variety of central (CNS) and peripheral (PNS) nervous system syndromes in AIDS patients. Among the PNS syndromes, a rapidly progressive lumbosacral polyradiculopathy is the most frequent, occurring in about 1% of AIDS patients (1-6). Cranial nerve involvement in this PNS CMV syndrome has been mentioned only rarely and only in occasional nerves (7,8). Our case is unique in the presence of multiple cranial neuropathies resulting from direct infection of each with CMV. The manifestations of CMV ventricular encephalitis are consistent with this previously described distinct clinical-pathological entity known to occur in HIV-infected patients (9). Another unique aspect in this case is the discrepancy between the minimal MRI findings in the periventricular regions in the presence of diffuse necrotizing ventriculo-encephalitis. A possible explanation for this is the ...
In a prospective study of 271 new patients with nasopharyngeal carcinoma, 36 (13.3%) were found to have cranial nerve involvement. Serous otitis media (SOM) was found in 98 (41.4%) of 237 patients who had undergone complete otologic assessment. The local control of tumor and actuarial survival of three subgroups of patients, namely, 80 patients with SOM only, 11 patients with cranial nerve palsy only, and 18 patients with both SOM and cranial nerve palsy, were analyzed. The local control of tumor was better in patients with SOM alone than in those with cranial nerve palsy alone; those patients with both SOM and cranial nerve involvement had worse local control as well as survival. As SOM is not uncommon in the diagnosis of nasopharyngeal carcinoma, and adult-onset SOM is otherwise distinctly uncommon, this provides a good opportunity for early recognition and, perhaps, better control of nasopharyngeal carcinoma ...
We observed that most CN palsies had 1 or more MRI findings of intracranial or orbital CN involvement; this may be a reason for the adverse prognostic significance of CN palsies, and patients with CN palsies are determined to be at stage T4.3. Several investigators have reported that the perineural tumor spread in patients with non-nasopharyngeal carcinoma of the head and neck is associated with an increased incidence of recurrence.18-21 However, in our series, MRI-detected CN involvement was not associated with the 3-year LRFS rate in NPC patients with local advanced disease. The primary treatment modality for NPC was radiation therapy, whereas that of other carcinomas of the head and neck was surgery. Lawrence and Cottel reported that postoperative radiotherapy of squamous cell carcinoma with perineural invasion resulted in a much improved survival probability when compared with that observed after conventional surgical excision.20 Radiation therapy (relatively large treatment volume) provided ...

OBJECTIVES: Functional reorganisation of the motor or sensory cortex has been demonstrated in animals after section of mixed peripheral nerves. Here functional changes in the motor cortex specifically after peripheral motor denervation in humans are investigated. METHODS: Functional MRI (fMRI) was used to study brain activation during a finger flexion-extension task in patients with a late onset, acquired pure motor neuropathy (n=6), contrasting results with those from patients with pure sensory neuropathies (n=4) or healthy controls (n=7). RESULTS: Increases in the extent of activation in the motor cortex both ipsilateral and contralateral to the hand moved were found in the patients with motor neuropathy. The neuroanatomical localisation of the mixed contralateral sensorimotor cortex activation volume was more posterior for the patients with motor neuropathy than for the healthy controls (mean difference, 12 mm, p|0.05). The pure sensory neuropathy group by contrast showed no change in the extent of
The second cranial nerve is called the optic nerve. It sends visual information from the eye to the brain. The third cranial nerve is called the oculomotor nerve. It is involved with eye movement, eyelid movement, and the function of the pupil and lens. The fourth cranial nerve is called the trochlear nerve and the sixth cranial nerve is called the abducens nerve. They each innervate an eye muscle involved in eye movement. The fifth cranial nerve is called the trigeminal nerve. It provides facial sensation (including corneal sensation).. ...

Anisocoria in the absence of orbital trauma. Abnormalities in a cranial nerve reflex indicate injury to the brainstem or the neural pathway connecting to the brainstem. Multiple cranial nerve deficits is highly suggestive of brainstem injury. The two most useful cranial nerve reflexes for rapid assessment of brainstem function are the gag reflex and the presence of physiologic nystagmus, otherwise known as the oculocephalic reflex. If these two reflexes are absent it strongly indicates significant brainstem injury and a guarded prognosis.. The segmental spinal reflexes should be evaluated when possible, without excessive manipulation of the patient. Abnormalities in thoracic and/or pelvic limb reflexes will help identify spinal trauma. Cases of brain injury without spinal injury tend to have normal or possibly exaggerated spinal reflexes.. Decerebrate posture: patient has opisthotonos and extensor rigidity of all four limbs. The animal is unresponsive and does not detect deep pain sensation. ...

Publication Year and Month: 1997 05. Abstract: Here we report a case of a 56-year-old male with post-poliomyelitis muscular atrophy (PPMA), who presented with cranial nerve signs and widespread atrophy of the extremities. He had suffered from poliomyelitis at the age of 2 years. After recovery from the acute stage, the paralysis remained in his left arm. He noticed muscle weakness of the right upper and lower extremities at the age of 45 years and the muscle atrophy progressed to his arms, hip and thigh at the age of 55 years. Neurological examination revealed muscle atrophy of the neck and disturbance of left V, VIII, IX, X and bilateral XI cranial nerves. We diagnosed this case as PPMA from his history and electromyographic and muscle biopsy findings which suggested chronic denervation. Among the 21 PPMA cases in the past in which the acute poliomyelitis had resulted in paralysis of the only one limb, ours was the only case that had muscle atrophy of all the limbs. Cranial nerve involvement is ...

TY - JOUR. T1 - Response of extra-axial tumors to stereotactically implanted high-activity 125l seeds. AU - Patil, Arun Angelo. AU - Kumar, Pradeep. AU - Leibrocka, Lyal G.. PY - 1995/1/1. Y1 - 1995/1/1. N2 - 125I seeds can deliver a very high dose of radiation (100-500 Gy) to a well-circumscribed area over their average life of 87 days, which enable them to destroy slow-growing extra-axial tumors after permanent implantation. Stereotactic implantation of 125I seeds was performed in 26 patients with extra-axial tumors, with a median follow-up of 32 months. No acute morbidity or mortality resulted from the procedure. Cranial nerve involvement in 5 patients was the only delayed complication. One patient developed radionecrosis outside the range of 125I dose distribution, which was felt to be due to the hyperfractionated external radiation the patient had received prior to 125I seed placement. All 26 patients showed tumor regression. The results indicate that this form of treatment is relatively ...
The act of swallowing is complex. Approximately 40 oral and pharyngeal (mouth and throat) muscles and multiple cranial nerves work together to accomplish two critical, life sustaining actions: breathing and swallowing. Weak oropharyngeal muscles can prevent effective and efficient transport of food, liquids and medication causing them to flow into an unprotected airway, also known as aspiration. Swallowing disorders, also known as dysphagia, are highly prevalent in stroke patients and are associated with increased mortality and morbidity, dehydration, pulmonary complications, and reduced rehabilitation potential. Therefore, it is critical to ensure Medicare patients have access to safe, effective therapies to improve their swallowing function, prevent further complications and continue to advance their rehabilitation ...

Germinomas typically arise in regions adjacent to the third ventricle, such as the pineal body and neurohypophysis, but they may be present also in the basal ganglia. Germinomas originating in the cerebellum are quite rare [5-11] (see Additional file 2: Table S1); in one study, only three of 153 intracranial GCTs were located in the cerebellum [12]. It is not difficult to diagnose intracranial GCTs when they have a typical location and radiographic features. However, an intracranial GCT located in the basal ganglia often is difficult to detect because enhancement is usually slight or absent [2]. Recent reports have emphasized the effectiveness of SWI in early detection of basal ganglia GCTs [13]. SWI can be used to detect blood products and accumulation of biologic metal, thereby providing additional information in evaluation of brain tumors. SWI may be useful also in the detection of intracranial GCTs, because this type of tumor is characterized by a high incidence of intra-tumor micro bleeds. ...

Lower cranial nerve (IX-XII) palsy is a rare condition with numerous causes, usually non-traumatic. In the literature it has been described only a few times after trauma, mostly accompanied by a fracture of the occipital condyle. Although these types of fractures have rarely been reported one could suspect they have been under-diagnosed. During the past decade they have been seen more frequently, most probably due to increased use of CT- and MRI-scanning. The purpose of this review is to increase the awareness of complications following injuries in the craniocervical region. We based this article on a retrospective review of the medical record of a 24-year old woman admitted to our trauma center after being involved in a car accident and a review of the literature on occipital condyle fractures associated with lower cranial nerve palsy. The multitraumatized patient had suffered a dislocated occipital condyle fracture. Months later she was diagnosed with palsy to cranial nerve IX-XII. Literature review

Onset of first symptom has been reported between 1-12 years, with a mean age of onset at 8 years. Clinical course can be divided into early (, 6 yrs age, predominance of respiratory symptoms) and late course (6-20 years of age, predominance of motor symptoms on superior limbs). Progression to involve other cranial nerve muscles occurs over a period of months or years. In the Gomez review facial nerve was affected in all cases while hypoglossal nerve was involved in all except one case. Other cranial nerves involved were vagus, trigeminal, spinal accessory nerve, abducent, occulomotor and glossopharyngeal in this order. Corticospinal tract signs were found in 2 of the 14 patients. The disease may progress to patients death in a period as short as 9 months or may have a slow evolution or may show plateaus. Post mortem examination of cases have found depletion of nerve cells in the nuclei of cranial nerves. The histologic alterations found in patient with Fazio-Londe disease were identical to ...
RESULTS: Primary CNSL was typically localized supratentorially (63%), with multiple (59%) or infiltrative (36%) lesions showing diffusion restriction (98%), often (87%) reaching the brain surface. In approximately 50% of patients, meningeal, ependymal or cranial nerve involvement was found. We detected significant differences in enhancement patterns between immunocompromised and immunocompetent patients; non-homogenous enhancement present in 50% of immunocompromised patients. We did not find any significant differences in MRI appearance between primary and secondary CNSL. Regression was evident after corticosteroid treatment in 52% of patients; however, in 16% of cases overall progression was observed ...
The mean follow-up duration was 84 months (median 75.5 months, range 24-216 months). In 118 patients (86%), the tumor volume was unchanged or had decreased at last follow-up. Kaplan-Meier analysis demonstrated radiographic progression-free survival at 5 and 10 years to be 95.4% and 69%, respectively. Fourteen patients (10%) developed new cranial nerve palsies following GKS. Factors associated with tumor control included younger age, a higher isodose, and smaller tumor volume. A longer follow-up duration was associated with either a decrease or increase in tumor volume. Fourteen patients (10%) experienced new or worsening cranial nerve deficits after treatment. Factors associated with this occurrence were larger pretreatment tumor volume, lower peripheral radiation dose, lower maximum dose, tumor progression, and longer follow-up. ...

Cranial Nerve 1- Olfaction This patient has difficulty identifying the smells presented. Loss of smell is anosmia. The most common cause is a cold (as in this patient) or nasal allergies. Other causes include trauma or a meningioma affecting the olfactory tracts. Anosmia is also seen in Kallman syndrome because of agenesis of the olfactory bulbs. Cranial Nerve 2- Visual acuity This patientâs visual acuity is being tested with a Rosenbaum chart. First the left eye is tested, then the right eye. He is tested with his glasses on so this represents corrected visual acuity. He has 20/70 vision in the left eye and 20/40 in the right. His decreased visual acuity is from optic nerve damage. Cranial Nerve II- Visual field The patients visual fields are being tested with gross confrontation. A right sided visual field deficit for both eyes is shown. This is a right hemianopia from a lesion behind the optic chiasm involving the left optic tract, radiation or striate cortex. Cranial Nerve II- Fundoscopy ...
Multiple cranial nerves may be involved (nerves V, VI, VII, IX, X, and XII can all be affected) and lead to orofacial malformations, abnormalities of tongue coordination, swallowing (bulbar muscle weakness), and drooling. Speech abnormalities are common. High risk for corneal abrasions. Usually the affected individuals are mentally normal. However, there is a 10% incidence of mild mental retardation. Occasionally peripheral neuropathy and pectoral muscle deficiency. Abnormalities of ventilation (central hypoventilation and idiopathic tachypnea) presumably result from brainstem abnormalities.

Diabetes accounts for approximately one-third of cases of neovascular glaucoma. Neovascular glaucoma is a rare type of glaucoma that often results in visual loss. Neovascular glaucoma can occur when new blood vessels grow on the iris, closing off fluid flow in the eye and raising the eye pressure. It can be very difficult to treat, which is why those with diabetes should get their eyes examined on a regular basis.. In addition, people with diabetes are 60 percent more likely to develop cataracts, which is a serious condition that causes the eyes lens to cloud and interfere with normal vision. Cataracts is a condition that tends to develop at an earlier age in people with diabetes.. Those with diabetes are also more at risk for developing microvascular cranial nerve palsies. Microvascular cranial nerve palsies involve the small bloods vessels that affect the muscles that move the eyes. Symptoms of this condition include not being about to move the eyes in different directions, causing double ...
EHV-1 usually manifests as a respiratory disease, but can occasionally mutate to a form that affects the nervous system. Infected horses may develop symptoms such as weakness or paralysis of the hind legs giving rise to the dog-sitting position, loss of tail and anal tone, inability to urinate or defecate, urine dribbling, cranial nerve deficits, recumbency, and death. No specific treatment is available for EHV-1, but general supportive therapy and care can aid recovery of affected horses. Anti-inflammatory agents may be helpful in minimizing damage to the spinal cord. The human drug acyclovir was used in a recent EHV-1 outbreak in Ohio, and efficacy of this treatment seems promising. ...
